Meanbastard Jr Posted June 8, 2012 Report Share Posted June 8, 2012 So I'm doin a bottom and top end rebuild since I blew the lower crank bearing on the right rod. I bought wiseco forged pistons and a wiseco crank( the crank is stock spec. Well I ordered the damn thing on eBay and the first crank I received ended up having at least a +4 stroke, and I need a stock crank. Anyway a 2 weeks later after sending them back that crank I finally get a stock length crank and the keyway on the primary gear side wasn't machined enough. Wtf so my question is is this common I thought wiseco cranks were second best to hot rod cranks. Man I wanna ride.... Quote Link to comment Share on other sites More sharing options...

Meanbastard Jr Posted June 8, 2012 Author Report Share Posted June 8, 2012 Pics?? Its not worth taking pics of you know when you slide the primary drive gear on the drive side with the key on the crank its should just slide right on this crank does not because the keyway is machined half assed.

Meanbastard Jr Posted June 8, 2012 Author Report Share Posted June 8, 2012 The key doesn't fit in at all? Not unless I hammer the shit outta it and if I do that the key doesn't seat right on the crank. man u got a 4mil wiseco crank for the price of a stock stroke?i would of sold that shit and made a profit then bought a new hotrods stock stroke Yeah I thought about it but too bad I have a conscious and I wouldn't have got that much more for it than what I paid for stock.

edgehanger Posted June 8, 2012 Report Share Posted June 8, 2012 Will the key slide in the slot and seat with out the gear on it? Could be the gear. I had this problem on a stock crank before and it turned out to be the gear itself had some trauma to it Quote Link to comment Share on other sites More sharing options...

Meanbastard Jr Posted June 8, 2012 Author Report Share Posted June 8, 2012 Neither the key or the hear is the problem. When I received the stroker crank the key and the gear slid in perfectly as well as with my busted stock crank the keyway on this new crank I got has some rough ridges in it as well...

Meanbastard Jr Posted June 8, 2012 Author Report Share Posted June 8, 2012 Is there anything I can do to make this damn crank work now? I was think about grinding down the key a lil but I don't exactly know how much to grind off. Or could I file downte key way? Any help would be much appreciated. Frigging wiseco says I have to RMA through the company I bought it from and it sucks cause I bought it on eBay from apex racing and they aren't responding.

I am not sure how much interference you are talking about but since you say you could beat in but it will not go flush to bottom of keyway on the crank I am going to assume we are not talking about much. They make small diamond files that will cut hardened steel but you would probably not end up with straight sides on the keyway. You would have to keep all the pressure towards the bottom of keyway while filing the sides so not to file the top of the keyway too sloppy. It is doable but not as precision as it should be done. I have also made step keys to fix similar problems. It would work best with a surface grinder or at least a mill though. You just grind the half of the key that fits in keyway taking the same off each side so your centers stay equal. Be sure to not be taking any material off the half that fits in the primary gear. Once again, doing this kind of shit with hand tools is a down and dirty fix at best. If you have a local machine shop it would be a breeze for someone to skim the crank slot until you had a good fit and the sides of the keyway would be nice and straight at the same time. Sounds like a nice build, I would either look in the local machine shop option or try to send it back. EBAY sucks in my opinion, I see some good deals but always seems like the troubles you can run into are not worth the little bit ya save. Good luck and let us know how it turns out for you.
